Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to United States Provisional Patent Application Serial No. 62/869,088, filed on July 1, 2019, the entire disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

[0002] This disclosure relates generally to a surface cleaning device for cleaning a surface.

BACKGROUND

[0003] A surface cleaning device, such as a broom, a sweeper, or a vacuum cleaner, can be used to clean a variety of surfaces, such as wood, tile, and carpeted floors. Surface cleaning devices can collect large debris, such as crumbs, dirt, and pebbles, from floors and other surfaces using suction and rotatable roller brushes. Surface cleaning devices may have too much or too little suction for a specific type of surface, resulting in inadequate cleaning. Debris, such as long animal fur, floss, string, and hair may become tangled in the roller brushes, which can prevent the roller brushes from rotating properly thereby decreasing the effectiveness of the surface cleaning device. It can be difficult to remove all debris from the roller brushes and such removal may not be possible or may result in damage to the surface cleaning device. Surface cleaning devices may have wheels to allow for movement over a surface. Wheels may restrict movement of the surface cleaning device, requiring more force to move the surface cleaning device thereby preventing full rotation of the surface cleaning device. This makes it particularly hard to clean in hard-to-reach surface areas. In addition, small debris, including dust-sized particles may remain on the surface thereby requiring additional cleaning.

[0004] A surface cleaning device, such as a mop or a cleaning cloth, can be used to clean small debris, including moisture, from a variety of hard surfaces, such as wood and tile floors. Instead of using a mop and bucket for cleaning the surface, mops can include a spray nozzle located on a front portion of the mop to spray cleaning fluid to the surface in front of the mop. The mop can then be pushed over the cleaning fluid to clean the surface.

[0005] Some surface cleaning devices include a combination of a sweeper and a mop, but they may require a two-step cleaning process. More specifically, the larger debris should be removed from the surface before the spray nozzle is activated to mop the floor. If larger debris is wet, neither the sweeper nor the mop features of the surface cleaning device can remove such debris from the surface. Therefore, the surface may need to be swept before being mopped. This process can be time consuming.

For example, after the debris, such as large, dry, debris, is swept into the sweeper assembly 110 and stored in the debris container 146, at least some of the debris, such as small particles of debris, can be removed from the surface by the cleaning pad 148. In other words, the surface cleaning device 100 can be configured as a dry mop with a sweeper within the surface cleaning device.

[0041] The surface cleaning device can include additional and/or fewer components and is not limited to those illustrated in FIGS. 1-3.

[0042] FIGS. 4-7 illustrate an exemplary surface cleaning device 200 in accordance with aspects of the present disclosure. The surface cleaning device 200 can be configured to remove debris by sweeping and by wet mopping in one step. As the user is moving the surface cleaning device 200 across the floor, the surface cleaning device 200 can be configured to first sweep the debris from the surface and then mop up any remaining debris from the floor. Rather than spraying liquid onto the surface in front of the device, the surface cleaning device 200 can dispense liquid directly onto a cleaning pad 248 to remove debris after larger debris has been removed by a sweeper assembly 210. For example, the surface cleaning device 200 can include a front portion that funnels large, dry debris from the surface into a sweeper assembly 210 to collect the debris into a debris container 246, and then liquid can be dispersed into the cleaning pad 248 behind a brush 250 to remove smaller debris from the surface.

[0043] In addition to the features of the surface cleaning device 100 illustrated and described in FIGS. 1-3, the surface cleaning device 200 can include additional components used in connection with a wet mop assembly. The wet mop assembly can include a fluid tank 216, one or more fluid lines, and a plurality of nozzles 222.

[0044] The surface cleaning device 200 can include a handle assembly 202 coupled to a cleaning head 206. The handle assembly 202 can include an elongated arm, such as a pole, having a tubular shape and extending between a top end and a bottom end. The elongated arm, or pole, can include a first segment at the top end and a second segment at the bottom end, and wherein the first segment is telescopingly received by the second segment. A handle 212 can be connected to the top end of the pole. A trigger 214 can be coupled to the handle assembly 202, such as the handle 212, and configured to release a fluid from the fluid tank 216. For example, when a user squeezes the trigger 214, the liquid gets pushed down into the cleaning head 206 and saturate the cleaning pad 248 and floor directly below the cleaning head 206. The surface cleaning device 200 can function as a self-saturating liquid system.

[0045] A cleaning head 206 can be coupled to the bottom end of the pole. A mounting mechanism can couple the cleaning head 206 to the bottom of the pole. The mounting mechanism can be a universal join allowing the elongated arm to pivot 360 degrees about the universal joint. The joint may be a thin universal joint positioned sideways. For example, one of the dimensions of the universal joint is thin. The join can attach the pole to the cleaning head 206 in a bridge-like configuration. The joint can be configured such that it minimally displaces any debris from the front of the cleaning head 206 to the back of the cleaning head 206.

[0046] The cleaning head 206 can include a base 240 having a top surface and a bottom surface, and a pair of tapered front portions, a rear portion, and a pair of side edges extending between the front and back portions. The cleaning head 206 can include a housing 236. The housing 236 can define an inlet opening 238 adjacent to the front edge of the base 240 of the cleaning head 206. The front portion of the base 240 can define a rectangular-shaped inlet notch in alignment with the inlet opening 238 of the housing 236. The cleaning head 206 can be formed in a bow-tie shape. The bow-tie shape of the cleaning head 206 can funnel dry debris into the sweeper head. For example, larger pieces of debris can funnel toward the front of the inlet notch and the sweeper head.

[0047] The cleaning head 206 can include a pair of tapered housing 236, such as a first and second tapered housing 266, 268, adjacent opposing sides of the housing 236. A switch 270 can be coupled to a first tapered housing 266. The switch 270 can be depressed, for example, by using a foot. A battery assembly 204 can be coupled to a second tapered housing 268. The cleaning head 206 can include one or more windows 272. The pair of adjacent tapered housing 266, 268 can include a pair of windows 272. The window 272 can be formed from transparent material or any other desired material. The window 272 can allow a user to view fluid disposed in the tapered front housing 266, 268.
